Question

A body $A$ is moving in a straight line with a constant speed of $10{ms}^{-1}$. Another body $B$ having same mass as that of $A$ is moving in a circular path with a constant speed of $10{ms}^{-1}$. The correct statement related to their acceleration is

• A. The acceleration of body $A$ is more than the acceleration of body $B$
• B. The acceleration of body $B$ is zero
• C. Only $B$ has acceleration
• D. The acceleration of both $A$ and $B$ are same

Answer 1

The correct option is C Only $B$ has acceleration

The body B moving in circular path with uniform speed 10m/s experiences a radial circulation directed towards centre due to change in direction, called centripetal acceleration.
